Liquefied hydrogen storage is a method of storing hydrogen, which is commonly used in the aerospace industry, and the temperature is - 253 ℃.
application area
When the hydrogen is cooled to - 253 ℃, the hydrogen can be liquefied. Liquid hydrogen storage has the largest mass energy density, which is a lightweight and compact way. However, the cost of hydrogen liquefaction is high, the energy loss is large (the energy required for hydrogen liquefaction is 30% of the heat production of liquefied hydrogen combustion), and there is evaporation loss. Liquid hydrogen storage technology was first used in aerospace, but it needs excellent thermal insulation device to prevent liquid hydrogen from boiling and vaporizing, which leads to a very large liquid storage tank.
